Furthermore, the present inventionrelates to the use of this composition as well as a method for enhancingplant growth, promoting plant health, and/or reducing overall damage ofplants and plant parts.

BACKGROUND OF THE INVENTION

In crop protection, there is a continuous need for applications thatimprove the health and/or the growth of plants. Healthier plantsgenerally result in higher yields and/or better quality of a plant orits products.

In order to promote plant health, fertilizers are employed worldwide,based on both inorganic and organic substances. A fertilizer may be asingle substance or a composition, and is used to provide nutrients toplants. A major breakthrough in the application of fertilizers was thedevelopment of nitrogen-based fertilizer by Justus von Liebig around1840. Fertilizers, however, can lead to soil acidification anddestabilization of nutrient balance in soil, including depletion ofminerals and enrichment of salt and heavy metals. In addition, excessivefertilizer use can lead to alteration of soil fauna as well ascontaminate surface water and ground water. Further, unhealthfulsubstances such as nitrate may become enriched in plants and fruits.

In addition, insecticides and fungicide are employed worldwide tocontrol pests. Synthetic insecticides or fungicides often arenon-specific and therefore can act on organisms other than the targetorganisms, including other naturally occurring beneficial organisms.Because of their chemical nature, they may also be toxic andnon-biodegradable. Consumers worldwide are increasingly conscious of thepotential environmental and health problems associated with theresiduals of chemicals, particularly in food products. This has resultedin growing consumer pressure to reduce the use or at least the quantityof chemical (i.e., synthetic) pesticides. Thus, there is a need tomanage food chain requirements while still allowing effective pestcontrol.

A further problem arising with the use of synthetic insecticides orfungicides is that the repeated and exclusive application of aninsecticide or fungicides often leads to selection of resistant animalpests or microorganisms. Normally, such strains are also cross-resistantagainst other active ingredients having the same mode of action. Aneffective control of the pathogens with said active compounds is thennot possible any longer. However, active ingredients having newmechanisms of action are difficult and expensive to develop.

The use of biological control agents (BCAs), which act as planthealth-enhancing and/or plant protection agents, is an alternative tofertilizers and synthetic pesticides. In some cases, the effectivenessof BCAs is not at the same level as for conventional insecticides andfungicides, especially in case of severe infection pressure.Consequently, in some circumstances, biological control agents, theirmutants and metabolites produced by them are, in particular in lowapplication rates, not entirely satisfactory. Thus, there is a constantneed for developing new plant health-enhancing and/or plant protectioncompositions, including biological control agents used in conjunctionwith synthetic fungicides and insecticides, to strive to fulfill theabove-mentioned requirements.

SUMMARY

In view of this, it was in particular an object of the present inventionto provide compositions which have an enhanced ability to improve plantgrowth and/or to enhance plant health or which exhibit enhanced activityagainst insects, mites, nematodes and/or phytopathogens.

Recombinant Exosporium-Producing Bacillus Cells Expressing FusionProteins

The fusion proteins contain a targeting sequence, an exosporium protein,or an exosporium protein fragment that targets the fusion protein to theexosporium of a Bacillus cereus family member and: (a) a plant growthstimulating protein or peptide; (b) a protein or peptide that protects aplant from a pathogen; (c) a protein or peptide that enhances stressresistance of a plant; (d) a plant binding protein or peptide; or (e) aplant immune system enhancer protein or peptide. When expressed inBacillus cereus family member bacteria, these fusion proteins aretargeted to the exosporium layer of the spore and are physicallyoriented such that the protein or peptide is displayed on the outside ofthe spore.

This Bacillus exosporium display (BEMD) system can be used to deliverpeptides, enzymes, and other proteins to plants (e.g., to plant foliage,fruits, flowers, stems, or roots) or to a plant growth medium such assoil. Peptides, enzymes, and proteins delivered to the soil or anotherplant growth medium in this manner persist and exhibit activity in thesoil for extended periods of time. Introduction of recombinantexosporium-producing Bacillus cells expressing the fusion proteinsdescribed herein into soil or the rhizosphere of a plant leads to abeneficial enhancement of plant growth in many different soilconditions. The use of the BEMD to create these enzymes allows them tocontinue to exert their beneficial results to the plant and therhizosphere over the first months of a plants life.

Bacillus is a genus of rod-shaped bacteria. The Bacillus cereus familyof bacteria includes the species Bacillus anthracis, Bacillus cereus,Bacillus thuringiensis, Bacillus mycoides, Bacillus pseudomycoides,Bacillus samanii, Bacillus gaemokensis, Bacillus toyoiensis, andBacillus weihenstephensis. Under stressful environmental conditions,Bacillus cereus family bacteria undergo sporulation and form ovalendospores that can stay dormant for extended periods of time. Theoutermost layer of the endospores is known as the exosporium andcomprises a basal layer surrounded by an external nap of hair-likeprojections. Filaments on the hair-like nap are predominantly formed bythe collagen-like glycoprotein BclA, while the basal layer is comprisedof a number of different proteins. Another collagen-related protein,BclB, is also present in the exosporium and exposed on endospores ofBacillus cereus family members.

BclA, the major constituent of the surface nap, has been shown to beattached to the exosporium with its amino-terminus (N-terminus)positioned at the basal layer and its carboxy-terminus (C-terminus)extending outward from the spore.

It was previously discovered that certain sequences from the N-terminalregions of BclA and BclB could be used to target a peptide or protein tothe exosporium of a Bacillus cereus endospore (see U.S. PatentPublication Nos. 2010/0233124 and 2011/0281316, and Thompson, et al.,“Targeting of the BclA and BclB Proteins to the Bacillus anthracis SporeSurface,” Molecular Microbiology, 70(2):421-34 (2008), the entirety ofeach of which is hereby incorporated by reference). It was also foundthat the BetA/BAS3290 protein of Bacillus anthracis localized to theexosporium.

In particular, amino acids 20-35 of BclA from Bacillus anthracis Sternestrain have been found to be sufficient for targeting to the exosporium.A sequence alignment of amino acids 1-41 of BclA (SEQ ID NO: 1) with thecorresponding N-terminal regions of several other Bacillus cereus familyexosporium proteins and Bacillus cereus family proteins having relatedsequences is shown in FIG. 1. As can be seen from FIG. 1, there is aregion of high-homology among all of the proteins in the regioncorresponding to amino acids 20-41 of BclA. However, in these sequences,the amino acids corresponding to amino acids 36-41 of BclA containsecondary structure and are not necessary for fusion proteinlocalization to the exosporium. The conserved targeting sequence regionof BclA (amino acids 20-35 of SEQ ID NO: 1) is shown in bold in FIG. 1and corresponds to the minimal targeting sequence needed forlocalization to the exosporium. A more highly conserved region spanningamino acids 25-35 of BclA within the targeting sequence is underlined inthe sequences in FIG. 1, and is the recognition sequence forExsFA/BxpB/ExsFB and homologs, which direct and assemble the describedproteins on the surface of the exosporium The amino acid sequences ofSEQ ID NOS. 3,5, and 7 in FIG. 1 are amino acids 1-33 of Bacillusanthracis Sterne strain BetA/BAS3290, a methionine followed by aminoacids 2-43 of Bacillus anthracis Sterne strain BAS4623, and amino acids1-34 of Bacillus anthracis Sterne strain BclB, respectively. (ForBAS4623, it was found that replacing the valine present at position 1 inthe native protein with a methionine resulted in better expression.) Ascan be seen from FIG. 1, each of these sequences contains a conservedregion corresponding to amino acids 20-35 of BclA (SEQ ID NO: 1; shownin bold), and a more highly conserved region corresponding to aminoacids 20-35 of BclA (underlined).

Additional proteins from Bacillus cereus family members also contain theconserved targeting region. In particular, in FIG. 1, SEQ ID NO: 9 isamino acids 1-30 of Bacillus anthracis Sterne strain BAS1882, SEQ ID NO:11 is amino acids 1-39 of the Bacillus weihenstephensis KBAB4 2280 geneproduct, SEQ ID NO: 13 is amino acids 1-39 of the Bacillusweihenstephensis KBAB4 3572 gene product, SEQ ID NO: 15 is amino acids1-49 of Bacillus cereus VD200 exosporium leader peptide, SEQ ID NO: 17is amino acids 1-33 of Bacillus cereus VD166 exosporium leader peptide,SEQ ID NO: 19 is amino acids 1-39 of Bacillus cereus VD200 hypotheticalprotein IKG_04663, SEQ ID NO: 21 is amino acids 1-39 of Bacillusweihenstephensis KBAB4 YVTN β-propeller protein, SEQ ID NO: 23 is aminoacids 1-30 of Bacillus weihenstephensis KBAB4 hypothetical proteinbcerkbab4_2363, SEQ ID NO: 25 is amino acids 1-30 of Bacillusweihenstephensis KBAB4 hypothetical protein bcerkbab4_2131, SEQ ID NO:27 is amino acids 1-36 of Bacillus weihenstephensis KBAB4 triple helixrepeat containing collagen, SEQ ID NO: 29 is amino acids 1-39 ofBacillus mycoides 2048 hypothetical protein bmyco0001_21660, SEQ ID NO:31 is amino acids 1-30 of Bacillus mycoides 2048 hypothetical proteinbmyc0001_22540, SEQ ID NO: 33 is amino acids 1-21 of Bacillus mycoides2048 hypothetical protein bmyc0001_21510, SEQ ID NO: 35 is amino acids1-22 of Bacillus thuringiensis 35646 collagen triple helix repeatprotein, SEQ ID NO: 43 is amino acids 1-35 of Bacillus cereushypothetical protein WP_69652, SEQ ID NO: 45 is amino acids 1-41 ofBacillus cereus exosporium leader WP016117717, SEQ ID NO: 47 is aminoacids 1-49 of Bacillus cereus exosporium peptide WP002105192, SEQ ID NO:49 is amino acids 1-38 of Bacillus cereus hypothetical protein WP87353,SEQ ID NO: 51 is amino acids 1-39 of Bacillus cereus exosporium peptide02112369, SEQ ID NO: 53 is amino acids 1-39 of Bacillus cereusexosporium protein WP016099770, SEQ ID NO: 55 is amino acids 1-36 ofBacillus thuringiensis hypothetical protein YP006612525, and SEQ ID NO:57 is amino acids 1-136 of Bacillus mycoides hypothetical proteinTIGR03720. As shown in FIG. 1, each of the N-terminal regions of theseproteins contains a region that is conserved with amino acids 20-35 ofBclA (SEQ ID NO: 1), and a more highly conserved region corresponding toamino acids 25-35 of BclA.

Any portion of BclA which includes amino acids 20-35 can be used as thetargeting sequence. In addition, full-length exosporium proteins orexosporium protein fragments can be used for targeting the fusionproteins to the exosporium. Thus, full-length BclA or a fragment of BclAthat includes amino acids 20-35 can be used for targeting to theexosporium. For example, full length BclA (SEQ ID NO: 2) or a midsizedfragment of BclA that lacks the carboxy-terminus such as SEQ ID NO: 59(amino acids 1-196 of BclA) can be used to target the fusion proteins tothe exosporium. Midsized fragments such as the fragment of SEQ ID NO: 59have less secondary structure than full length BclA and has been foundto be suitable for use as a targeting sequence. The targeting sequencecan also comprise much shorter portions of BclA which include aminoacids 20-35, such as SEQ ID NO: 1 (amino acids 1-41 of BclA), aminoacids 1-35 of SEQ ID NO: 1, amino acids 20-35 of SEQ ID NO: 1, or SEQ IDNO: 60 (a methionine residue linked to amino acids 20-35 of BclA). Evenshorter fragments of BclA which include only some of amino acids 20-35also exhibit the ability to target fusion proteins to the exosporium.For example, the targeting sequence can comprise amino acids 22-31 ofSEQ ID NO: 1, amino acids 22-33 of SEQ ID NO: 1, or amino acids 20-31 ofSEQ ID NO: 1.

Thus, any portion ofthese proteins that includes the above-listed corresponding amino acidscan serve as the targeting sequence.

Furthermore, any amino acid sequence comprising amino acids 20-35 ofBclA, or any of the above-listed corresponding amino acids can serve asthe targeting sequence.

Moreover, exosporium proteins having a high degree of sequence identitywith any of the full-length exosporium proteins or the exosporiumprotein fragments described above can also be used to target a peptideor protein to the exosporium of a Bacillus cereus family member.

Fusion Proteins

The fusion proteins can comprise a targeting sequence, an exosporiumprotein, or an exosporium protein fragment, and at least one plantgrowth stimulating protein or peptide. The plant growth stimulatingprotein or peptide can comprise a peptide hormone, a non-hormonepeptide, an enzyme involved in the production or activation of a plantgrowth stimulating compound or an enzyme that degrades or modifies abacterial, fungal, or plant nutrient source. The targeting sequence,exosporium protein, or exosporium protein fragment can be any of thetargeting sequences, exosporium proteins, or exosporium proteinfragments described above.

The fusion proteins can comprise a targeting sequence, an exosporiumprotein, or an exosporium protein fragment, and at least one protein orpeptide that protects a plant from a pathogen. The targeting sequence,exosporium protein, or exosporium protein fragment can be any of thetargeting sequences, exosporium proteins, or exosporium proteinfragments described above.

The fusion protein can be made using standard cloning and molecularbiology methods known in the art. For example, a gene encoding a proteinor peptide (e.g., a gene encoding a plant growth stimulating protein orpeptide) can be amplified by polymerase chain reaction (PCR) and ligatedto DNA coding for any of the above-described targeting sequences to forma DNA molecule that encodes the fusion protein. The DNA moleculeencoding the fusion protein can be cloned into any suitable vector, forexample a plasmid vector. The vector suitably comprises a multiplecloning site into which the DNA molecule encoding the fusion protein canbe easily inserted. The vector also suitably contains a selectablemarker, such as an antibiotic resistance gene, such that bacteriatransformed, transfected, or mated with the vector can be readilyidentified and isolated. Where the vector is a plasmid, the plasmidsuitably also comprises an origin of replication. The DNA encoding thefusion protein is suitably under the control of a sporulation promoterwhich will cause expression of the fusion protein on the exosporium of aB. cereus family member endospore (e.g., a native bc1A promoter from aB. cereus family member). Alternatively, DNA coding for the fusionprotein can be integrated into the chromosomal DNA of the B. cereusfamily member host.

The fusion protein can also comprise additional polypeptide sequencesthat are not part of the targeting sequence, exosporium protein,exosporium protein fragment, or the plant growth stimulating protein orpeptide, the protein or peptide that protects a plant from a pathogen,the protein or peptide that enhances stress resistance in a plant, orthe plant binding protein or peptide. For example, the fusion proteincan include tags or markers to facilitate purification or visualizationof the fusion protein (e.g., a polyhistidine tag or a fluorescentprotein such as GFP or YFP) or visualization of recombinantexosporium-producing Bacillus cells spores expressing the fusionprotein.

Expression of fusion proteins on the exosporium using the targetingsequences, exosporium proteins, and exosporium protein fragmentsdescribed herein is enhanced due to a lack of secondary structure in theamino-termini of these sequences, which allows for native folding of thefused proteins and retention of activity. Proper folding can be furtherenhanced by the inclusion of a short amino acid linker between thetargeting sequence, exosporium protein, exosporium protein fragment, andthe fusion partner protein.

Thus, any of the fusion proteins described herein can comprise an aminoacid linker between the targeting sequence, the exosporium protein, orthe exosporium protein fragment and the plant growth stimulating proteinor peptide, the protein or peptide that protects a plant from apathogen, the protein or peptide that enhances stress resistance in aplant, or the plant binding protein or peptide.

The linker can comprise a polyalanine linker or a polyglycine linker. Alinker comprising a mixture of both alanine and glycine residues canalso be used. For example, where the targeting sequence comprises SEQ IDNO: 1, a fusion protein can have one of the following structures:

-   -   No linker: SEQ ID NO: 1—Fusion Partner Protein    -   Alanine Linker: SEQ ID NO: 1—An—Fusion Partner Protein    -   Glycine Linker: SEQ ID NO: 1—Gn—Fusion Partner Protein    -   Mixed Alanine and Glycine Linker: SEQ ID NO: 1—(A/G)n—Fusion        Partner Protein    -   where An, Gn, and (A/G)n are any number of alanines, any number        of glycines, or any number of a mixture of alanines and        glycines, respectively. For example, n can be 1 to 25, and is        preferably 6 to 10. Where the linker comprises a mixture of        alanine and glycine residues, any combination of glycine and        alanine residues can be used. In the above structures, “Fusion        Partner Protein” represents the plant growth stimulating protein        or peptide, the protein or peptide that protects a plant from a        pathogen, the protein or peptide that enhances stress resistance        in a plant, or the plant binding protein or peptide.

Alternatively or in addition, the linker can comprise a proteaserecognition site. Inclusion of a protease recognition site allows fortargeted removal, upon exposure to a protease that recognizes theprotease recognition site, of the plant growth stimulating protein orpeptide, the protein or peptide that protects a plant from a pathogen,the protein or peptide that enhances stress resistance in a plant, orthe plant binding protein or peptide.

The protein or peptide that protects a plant from a pathogen can also bea protein or peptide that has insecticidal activity, helminthicidalactivity, suppresses insect or worm predation, or a combination thereof.For example, the protein or peptide that protects a plant from apathogen can comprise an insecticidal bacterial toxin (e.g., a VIPinsecticidal protein), an endotoxin, a Cry toxin (e.g., a Cry toxin fromBacillus thuringiensis), a protease inhibitor protein or peptide (e.g.,a trypsin inhibitor or an arrowhead protease inhibitor), a cysteineprotease, or a chitinase. Where the Cry toxin is a Cry toxin fromBacillus thuringiensis, the Cry toxin can be a Cry5B protein or a Cry21Aprotein. Cry5B and Cry21A have both insecticidal and nematocidalactivity.

The protein that protects a plant from a pathogen can comprise anenzyme. Suitable enzymes include proteases and lactonases. The proteasesand lactonases can be specific for a bacterial signaling molecule (e.g.,a bacterial lactone homoserine signaling molecule).

For example, the enzyme can comprisea β-1,3-glucanase, a β-1,4-glucanase, a β-1,6-glucanase, a chitosinase,a chitinase, a chitosinase-like enzyme, a lyticase, a peptidase, aproteinase, a protease (e.g., an alkaline protease, an acid protease, ora neutral protease), a mutanolysin, a stapholysin, or a lysozyme.

Proteins and Peptides that Enhance Stress Resistance in Plants

The fusion proteins can comprise a targeting sequence, exosporiumprotein, or exosporium protein fragment and at least one protein orpeptide that enhances stress resistance in a plant.

For example, the protein or peptide that enhances stress resistance in aplant comprises an enzyme that degrades a stress-related compound.Stress-related compounds include, but are not limited to,aminocyclopropane-1-carboxylic acid (ACC), reactive oxygen species,nitric oxide, oxylipins, and phenolics.

The enzymethat degrades a stress-related compound can comprise a superoxidedismutase, an oxidase, a catalase, an aminocyclopropane-1-carboxylicacid deaminase, a peroxidase, an antioxidant enzyme, or an antioxidantpeptide.

The protein or peptide that enhances stress resistance in a plant canalso comprise a protein or peptide that protects a plant from anenvironmental stress. The environmental stress can comprise, forexample, drought, flood, heat, freezing, salt, heavy metals, low pH,high pH, or a combination thereof. For instance, the protein or peptidethat protects a plant from an environmental stress can comprises an icenucleation protein, a prolinase, a phenylalanine ammonia lyase, anisochorismate synthase, an isochorismate pyruvate lyase, or a cholinedehydrogenase.

The plant binding protein or peptide can be anyprotein or peptide that is capable of specifically or non-specificallybinding to any part of a plant (e.g., a plant root or an aerial portionof a plant such as a leaf, stem, flower, or fruit) or to plant matter.Thus, for example, the plant binding protein or peptide can be a rootbinding protein or peptide, or a leaf binding protein or peptide.

Suitable plant binding proteins and peptides include adhesins (e.g.,rhicadhesin), flagellins, omptins, lectins, expansins, biofilmstructural proteins (e.g., TasA or YuaB) pilus proteins, curlusproteins, intimins, invasins, agglutinins, and afimbrial proteins.

Recombinant Bacillus that Express the Fusion Proteins

The fusion proteins described herein can be expressed by recombinantexosporium-producing Bacillus cells. The fusion protein can be any ofthe fusion proteins discussed above.

The recombinant exosporium-producing Bacillus cells can coexpress two ormore of any of the fusion proteins discussed above. For example, therecombinant exosporium-producing Bacillus cells can coexpress at leastone fusion protein that comprises a plant binding protein or peptide,together with at least one fusion protein comprising a plant growthstimulating protein or peptide, at least one fusion protein comprising aprotein or peptide that protects a plant from a pathogen, or at leastone protein or peptide that enhances stress resistance in a plant.

The recombinant exosporium-producing Bacillus cells can compriseBacillus anthracis, Bacillus cereus, Bacillus thuringiensis, Bacillusmycoides, Bacillus pseudomycoides, Bacillus samanii, Bacillusgaemokensis, Bacillus weihenstephensis, Bacillus toyoiensis or acombination thereof. For example, the recombinant exosporium-producingBacillus cells can comprise Bacillus cereus, Bacillus thuringiensis,Bacillus pseudomycoides, or Bacillus mycoides. In particular, therecombinant exosporium-producing Bacillus cells can comprise Bacillusthuringiensis or Bacillus mycoides.

To generate a recombinant exosporium-producing Bacillus cells expressinga fusion protein, any Bacillus cereus family member can be conjugated,transduced, or transformed with a vector encoding the fusion proteinusing standard methods known in the art (e.g., by electroporation). Thebacteria can then be screened to identify transformants by any methodknown in the art. For example, where the vector includes an antibioticresistance gene, the bacteria can be screened for antibiotic resistance.Alternatively, DNA encoding the fusion protein can be integrated intothe chromosomal DNA of a B. cereus family member host. The recombinantexosporium-producing Bacillus cells can then exposed to conditions whichwill induce sporulation. Suitable conditions for inducing sporulationare known in the art. For example, the recombinant exosporium-producingBacillus cells can be plated onto agar plates, and incubated at atemperature of about 30° C. for several days (e.g., 3 days).

Inactivated strains, non-toxic strains, or genetically manipulatedstrains of any of the above species can also suitably be used. Forexample, a Bacillus thuringiensis that lacks the Cry toxin can be used.Alternatively or in addition, once the recombinant B. cereus familyspores expressing the fusion protein have been generated, they can beinactivated to prevent further germination once in use. Any method forinactivating bacterial spores that is known in the art can be used.Suitable methods include, without limitation, heat treatment, gammairradiation, x-ray irradiation, UV-A irradiation, UV-B irradiation,chemical treatment (e.g., treatment with gluteraldehyde, formaldehyde,hydrogen peroxide, acetic acid, bleach, or any combination thereof), ora combination thereof. Alternatively, spores derived from nontoxigenicstrains, or genetically or physically inactivated strains, can be used.

Recombinant Exosporium-Producing Bacillus Cells Having Plant-GrowthPromoting Effects and/or Other Beneficial Attributes

Many Bacillus cereus family member strains have inherent beneficialattributes. For example, some strains have plant-growth promotingeffects. Any of the fusion proteins described herein can be expressed insuch strains.

For example, the recombinant exosporium-producing Bacillus cells cancomprise a plant-growth promoting strain of bacteria.

The plant-growth promoting strain of bacteria can comprise a strain ofbacteria that produces an insecticidal toxin (e.g., a Cry toxin),produces a fungicidal compound (e.g., a (β-1,3-glucanase, a chitosinase,a lyticase, or a combination thereof), produces a nematocidal compound(e.g., a Cry toxin), produces a bactericidal compound, is resistant toone or more antibiotics, comprises one or more freely replicatingplasmids, binds to plant roots, colonizes plant roots, forms biofilms,solubilizes nutrients, secretes organic acids, or any combinationthereof.

For example, where the recombinant exosporium-producing Bacillus cellscomprises a plant-growth promoting strain of bacteria, the plantgrowth-promoting strain of bacteria can comprise Bacillus mycoides BT155(NRRL No. B-50921), Bacillus mycoides EE118 (NRRL No. B-50918), Bacillusmycoides EE141 (NRRL No. B-50916), Bacillus mycoides BT46-3 (NRRL No.B-50922), Bacillus cereus family member EE128 (NRRL No. B-50917),Bacillus thuringiensis BT013A (NRRL No. B-50924), or Bacillus cereusfamily member EE349 (NRRL No. B-50928). Bacillus thuringiensis BT013A isalso known as Bacillus thuringiensis 4Q7. Each of these strains wasdeposited with the United States Department of Agriculture (USDA)Agricultural Research Service (ARS), having the address 1815 NorthUniversity Street, Peoria, Ill. 61604, U.S.A., on Mar. 10, 2014, and isidentified by the NRRL deposit number provided in parentheses.

These plant-growth promoting strains were isolated from the rhizospheresof various vigorous plants and were identified by their 16S rRNAsequences, and through biochemical assays. The strains were identifiedat least to their genus designation by means of conventionalbiochemistry and morphological indicators. Biochemical assays forconfirmed

Gram-positive strains such as Bacillus included growth on PEA medium andnutrient agar, microscopic examination, growth on 5% and 7.5% NaClmedium, growth at pH 5 and pH 9, growth at 42° C. and 50° C., theability to produce acid upon fermentation with cellobiose, lactose,glycerol, glucose, sucrose, d-mannitol, and starch; fluorescent pigmentproduction; gelatin hydrolysis; nitrate reduction; catalase production,starch hydrolysis; oxidase reaction, urease production and motility.

For example, the recombinant exosporium-producing Bacillus cellscomprising a plant-growth promoting strain of bacteria can compriseBacillus mycoides BT155, Bacillus mycoides EE141, or Bacillusthuringiensis BT013A. The recombinant exosporium-producing Bacilluscells can express any of the fusion proteins described herein, e.g., afusion protein comprising the targeting sequence of SEQ ID NO: 60 and anon-hormone peptide (e.g., kunitz trypsin inhibitor (KTI)), an enzymeinvolved in the production or activation of a plant growth stimulatingcompound (e.g., a chitosinase), a plant binding protein or peptide(e.g., TasA); a protein or peptide that protects a plant from a pathogen(e.g., TasA), or an enzyme that degrades or modifies a bacterial,fungal, or plant nutrient source (e.g., a phosphatase such as PhoA orphytase, or an endoglucanase).

Promoters

In any of the recombinant exosporium-producing Bacillus cells describedherein, the fusion protein can be expressed under the control of apromoter that is native to the targeting sequence, the exosporiumprotein, or the exosporium protein fragment of the fusion protein. Forexample, where the fusion protein comprises a targeting sequence derivedfrom B. anthracis Sterne BclA (e.g., amino acids 20-35 of SEQ ID NO: 1,amino acids 1-35 of SEQ ID NO: 1, SEQ ID NO: 1, or SEQ ID NO: 60) orwhere the fusion protein comprises full length BclA (SEQ ID NO: 2) or afragment of full length BclA (e.g., SEQ ID NO: 59), the fusion proteincan be expressed under the control of a promoter that is normallyassociated with the BclA gene in the genome of B. anthracis Sterne(e.g., the promoter of SEQ ID NO: 85).

Alternatively, the fusion protein can be expressed under the control ofa high-expression sporulation promoter. In some cases, the promoter thatis native to the targeting sequence, exosporium protein, or exosporiumprotein fragment will be a high-expression sporulation promoter. Inother cases, the promoter that is native to the targeting sequence,exosporium protein, or exosporium protein fragment will not be ahigh-expression sporulation promoter. In the latter cases, it may beadvantageous to replace the native promoter with a high-expressionsporulation promoter. Expression of the fusion protein under the controlof a high-expression sporulation promoter provides for increasedexpression of the fusion protein on the exosporium of the Bacilluscereus family member.

The high-expression sporulation promoter can comprise one or moresigma-K sporulation-specific polymerase promoter sequences.

Theapplication forms may comprise further crop protection agents and/orpesticidal agents, and/or activity-enhancing adjuvants such aspenetrants, examples being vegetable oils such as, for example, rapeseedoil, sunflower oil, mineral oils such as, for example, liquid paraffins,alkyl esters of vegetable fatty acids, such as rapeseed oil or soybeanoil methyl esters, or alkanol alkoxylates, and/or spreaders such as, forexample, alkylsiloxanes and/or salts, examples being organic orinorganic ammonium or phosphonium salts, examples being ammoniumsulphate or diammonium hydrogen phosphate, and/or retention promoterssuch as dioctyl sulphosuccinate or hydroxypropylguar polymers and/orhumectants such as glycerol and/or fertilizers such as ammonium,potassium or phosphorous fertilizers, for example.

Examples of typical formulations include water-soluble liquids (SL),emulsifiable concentrates (EC), emulsions in water (EW), suspensionconcentrates (SC, SE, FS, OD), water-dispersible granules (WG), granules(GR) and capsule concentrates (CS); these and other possible types offormulation are described, for example, by Crop Life International andin Pesticide Specifications, Manual on Development and Use of FAO andWHO Specifications for Pesticides, FAO Plant Production and ProtectionPapers—173, prepared by the FAO/WHO Joint Meeting on PesticideSpecifications, 2004, ISBN: 9251048576. The formulations may compriseactive agrochemical compounds other than one or more active compounds ofthe invention.

The formulations or application forms in question preferably compriseauxiliaries, such as extenders, solvents, spontaneity promoters,carriers, emulsifiers, dispersants, frost protectants, biocides,thickeners and/or other auxiliaries, such as adjuvants, for example. Anadjuvant in this context is a component which enhances the biologicaleffect of the formulation, without the component itself having abiological effect. Examples of adjuvants are agents which promote theretention, spreading, attachment to the leaf surface, or penetration.

These formulations are produced in a known manner, for example by mixingthe active compounds with auxiliaries such as, for example, extenders,solvents and/or solid carriers and/or further auxiliaries, such as, forexample, surfactants. The formulations are prepared either in suitableplants or else before or during the application.

Suitable for use as auxiliaries are substances which are suitable forimparting to the formulation of the active compound or the applicationforms prepared from these formulations (such as, e.g., usable cropprotection agents, such as spray liquors or seed dressings) particularproperties such as certain physical, technical and/or biologicalproperties.

Suitable extenders are, for example, water, polar and nonpolar organicchemical liquids, for example from the classes of the aromatic andnon-aromatic hydrocarbons (such as paraffins, alkylbenzenes,alkylnaphthalenes, chlorobenzenes), the alcohols and polyols (which, ifappropriate, may also be substituted, etherified and/or esterified), theketones (such as acetone, cyclohexanone), esters (including fats andoils) and (poly)ethers, the unsubstituted and substituted amines,amides, lactams (such as N-alkylpyrrolidones) and lactones, thesulphones and sulphoxides (such as dimethyl sulphoxide).

If the extender used is water, it is also possible to employ, forexample, organic solvents as auxiliary solvents. Essentially, suitableliquid solvents are: aromatics such as xylene, toluene oralkylnaphthalenes, chlorinated aromatics and chlorinated aliphatichydrocarbons such as chlorobenzenes, chloroethylenes or methylenechloride, aliphatic hydrocarbons such as cyclohexane or paraffins, forexample petroleum fractions, mineral and vegetable oils, alcohols suchas butanol or glycol and also their ethers and esters, ketones such asacetone, methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone,strongly polar solvents such as dimethylformamide and dimethylsulphoxide, and also water.

In principle it is possible to use all suitable solvents. Suitablesolvents are, for example, aromatic hydrocarbons, such as xylene,toluene or alkylnaphthalenes, for example, chlorinated aromatic oraliphatic hydrocarbons, such as chlorobenzene, chloroethylene ormethylene chloride, for example, aliphatic hydrocarbons, such ascyclohexane, for example, paraffins, petroleum fractions, mineral andvegetable oils, alcohols, such as methanol, ethanol, isopropanol,butanol or glycol, for example, and also their ethers and esters,ketones such as acetone, methyl ethyl ketone, methyl isobutyl ketone orcyclohexanone, for example, strongly polar solvents, such as dimethylsulphoxide, and water.

All suitable carriers may in principle be used. Suitable carriers are inparticular: for example, ammonium salts and ground natural minerals suchas kaolins, clays, talc, chalk, quartz, attapulgite, montmorillonite ordiatomaceous earth, and ground synthetic minerals, such as finelydivided silica, alumina and natural or synthetic silicates, resins,waxes and/or solid fertilizers. Mixtures of such carriers may likewisebe used. Carriers suitable for granules include the following: forexample, crushed and fractionated natural minerals such as calcite,marble, pumice, sepiolite, dolomite, and also synthetic granules ofinorganic and organic meals, and also granules of organic material suchas sawdust, paper, coconut shells, maize cobs and tobacco stalks.

Liquefied gaseous extenders or solvents may also be used. Particularlysuitable are those extenders or carriers which at standard temperatureand under standard pressure are gaseous, examples being aerosolpropellants, such as halogenated hydrocarbons, and also butane, propane,nitrogen and carbon dioxide.

Examples of emulsifiers and/or foam-formers, dispersants or wettingagents having ionic or nonionic properties, or mixtures of thesesurface-active substances, are salts of polyacrylic acid, salts oflignosulphonic acid, salts of phenolsulphonic acid ornaphthalenesulphonic acid, polycondensates of ethylene oxide with fattyalcohols or with fatty acids or with fatty amines, with substitutedphenols (preferably alkylphenols or arylphenols), salts ofsulphosuccinic esters, taurine derivatives (preferably alkyltaurates),phosphoric esters of polyethoxylated alcohols or phenols, fatty acidesters of polyols, and derivatives of the compounds containingsulphates, sulphonates and phosphates, examples being alkylarylpolyglycol ethers, alkylsulphonates, alkyl sulphates, arylsulphonates,protein hydrolysates, lignin-sulphite waste liquors and methylcellulose.The presence of a surface-active substance is advantageous if one of theactive compounds and/or one of the inert carriers is not soluble inwater and if application takes place in water.

Further auxiliaries that may be present in the formulations and in theapplication forms derived from them include colorants such as inorganicpigments, examples being iron oxide, titanium oxide, Prussian Blue, andorganic dyes, such as alizarin dyes, azo dyes and metal phthalocyaninedyes, and nutrients and trace nutrients, such as salts of iron,manganese, boron, copper, cobalt, molybdenum and zinc.

Stabilizers, such as low-temperature stabilizers, preservatives,antioxidants, light stabilizers or other agents which improve chemicaland/or physical stability may also be present. Additionally present maybe foam-formers or defoamers.

Furthermore, the formulations and application forms derived from themmay also comprise, as additional auxiliaries, stickers such ascarboxymethylcellulose, natural and synthetic polymers in powder,granule or latex form, such as gum arabic, polyvinyl alcohol, polyvinylacetate, and also natural phospholipids, such as cephalins andlecithins, and synthetic phospholipids. Further possible auxiliariesinclude mineral and vegetable oils.

There may possibly be further auxiliaries present in the formulationsand the application forms derived from them. Examples of such additivesinclude fragrances, protective colloids, binders, adhesives, thickeners,thixotropic substances, penetrants, retention promoters, stabilizers,sequestrants, complexing agents, humectants and spreaders. Generallyspeaking, the active compounds may be combined with any solid or liquidadditive commonly used for formulation purposes.

Suitable retention promoters include all those substances which reducethe dynamic surface tension, such as dioctyl sulphosuccinate, orincrease the viscoelasticity, such as hydroxypropylguar polymers, forexample.

Suitable penetrants in the present context include all those substanceswhich are typically used in order to enhance the penetration of activeagrochemical compounds into plants. Penetrants in this context aredefined in that, from the (generally aqueous) application liquor and/orfrom the spray coating, they are able to penetrate the cuticle of theplant and thereby increase the mobility of the active compounds in thecuticle. This property can be determined using the method described inthe literature (Baur, et al., 1997, Pesticide Science, 51, 131-152).Examples include alcohol alkoxylates such as coconut fatty ethoxylate(10) or isotridecyl ethoxylate (12), fatty acid esters such as rapeseedor soybean oil methyl esters, fatty amine alkoxylates such astallowamine ethoxylate (15), or ammonium and/or phosphonium salts suchas ammonium sulphate or diammonium hydrogen phosphate, for example.

The formulations preferably comprise between 0.0001% and 98% by weightof active compound or, with particular preference, between 0.01% and 95%by weight of active compound, more preferably between 0.5% and 90% byweight of active compound, based on the weight of the formulation. Thecontent of the active compound is defined as the sum of the recombinantexosporium-producing Bacillus cells and the at least one particularinsecticide disclosed herein.

The active compound content of the application forms (crop protectionproducts) prepared from the formulations may vary within wide ranges.The active compound concentration of the application forms may besituated typically between 0.0001% and 95% by weight of active compound,preferably between 0.0001% and 1% by weight, based on the weight of theapplication form. Application takes place in a customary manner adaptedto the application forms.

Furthermore, in one aspect of the present invention a kit of parts isprovided comprising a recombinant exosporium-producing Bacillus cellsand at least one particular insecticide disclosed herein in asynergistically effective amount in a spatially separated arrangement.

In a further embodiment of the present invention the above-mentioned kitof parts further comprises at least one additional fungicide and/or atleast one particular insecticide disclosed herein. The fungicide and/orthe insecticide can be present either in the recombinantexosporium-producing Bacillus cells component of the kit of parts or inthe insecticide component of the kit of parts being spatially separatedor in both of these components. Preferably, the fungicide and/or theinsecticide are present in the recombinant exosporium-producing Bacilluscells component.

Moreover, the kit of parts according to the present invention canadditionally comprise at least one auxiliary selected from the groupconsisting of extenders, solvents, spontaneity promoters, carriers,emulsifiers, dispersants, frost protectants, thickeners and adjuvants asmentioned below. This at least one auxiliary can be present either inthe recombinant exosporium-producing Bacillus cells component of the kitof parts or in the insecticide component of the kit of parts beingspatially separated or in both of these components.

In another aspect of the present invention the composition as describedabove is used for reducing overall damage of plants and plant parts aswell as losses in harvested fruits or vegetables caused by insects,mites, nematodes and/or phytopathogens.

Furthermore, in another aspect of the present invention the compositionas described above increases the overall plant health.

The term “plant health” generally comprises various sorts ofimprovements of plants that are not connected to the control of pests.For example, advantageous properties that may be mentioned are improvedcrop characteristics including: emergence, crop yields, protein content,oil content, starch content, more developed root system, improved rootgrowth, improved root size maintenance, improved root effectiveness,improved stress tolerance (e.g., against drought, heat, salt, UV, water,cold), reduced ethylene (reduced production and/or inhibition ofreception), tillering increase, increase in plant height, bigger leafblade, less dead basal leaves, stronger tillers, greener leaf color,pigment content, photosynthetic activity, less input needed (such asfertilizers or water), less seeds needed, more productive tillers,earlier flowering, early grain maturity, less plant verse (lodging),increased shoot growth, enhanced plant vigor, increased plant stand andearly and better germination.

With regard to the use according to the present invention, improvedplant health preferably refers to improved plant characteristicsincluding: crop yield, more developed root system (improved rootgrowth), improved root size maintenance, improved root effectiveness,tillering increase, increase in plant height, bigger leaf blade, lessdead basal leaves, stronger tillers, greener leaf color, photosyntheticactivity, more productive tillers, enhanced plant vigor, and increasedplant stand.

With regard to the present invention, improved plant health preferablyespecially refers to improved plant properties selected from crop yield,more developed root system, improved root growth, improved root sizemaintenance, improved root effectiveness, tittering increase, andincrease in plant height.

The effect of a composition according to the present invention on planthealth as defined herein can be determined by comparing plants which aregrown under the same environmental conditions, whereby a part of saidplants is treated with a composition according to the present inventionand another part of said plants is not treated with a compositionaccording to the present invention. Instead, said other part is nottreated at all or treated with a placebo (i.e., an application without acomposition according to the invention such as an application withoutall active ingredients (i.e., without the recombinantexosporium-producing Bacillus cereus family member-based biologicalcontrol agent as described herein and without an insecticide asdescribed herein), or an application without the recombinantexosporium-producing Bacillus cereus family member-based biologicalcontrol agent as described herein, or an application without aninsecticide as described herein.

The composition according to the present invention may be applied in anydesired manner, such as in the form of a seed coating, soil drench,and/or directly in-furrow and/or as a foliar spray and applied eitherpre-emergence, post-emergence or both. In other words, the compositioncan be applied to the seed, the plant or to harvested fruits andvegetables or to the soil wherein the plant is growing or wherein it isdesired to grow (plant's locus of growth).

Reducing the overall damage of plants and plant parts often results inhealthier plants and/or in an increase in plant vigor and yield.

Preferably, the composition according to the present invention is usedfor treating conventional or transgenic plants or seed thereof.

The present invention also relates to methods for stimulating plantgrowth using any of the compositions described above comprisingrecombinant exosporium-producing

Bacillus cells that express a fusion protein and at least one particularinsecticide disclosed herein. The method for stimulating plant growthcomprises applying to a plant, a plant part, to the locus surroundingthe plant or in which the plant will be planted (e.g., soil or othergrowth medium) a composition comprising recombinant exosporium-producingBacillus cells that express a fusion protein comprising: (i) at leastone plant growth stimulating protein or peptide; and (ii) a targetingsequence, exosporium protein, or exosporium protein fragment, and atleast one further particular insecticide disclosed herein in asynergistically effective amount.

In another aspect of the present invention a method for reducing overalldamage of plants and plant parts as well as losses in harvested fruitsor vegetables caused by insects, mites, nematodes and/or phytopathogensis provided comprising the step of simultaneously or sequentiallyapplying the recombinant exosporium-producing Bacillus cells and atleast one particular insecticide disclosed herein in a synergisticallyeffective amount.

In another embodiment of the present invention, the compositioncomprises at least one fungicide and/or at least one insecticide inaddition to the recombinant exosporium-producing Bacillus cells and theparticular insecticide disclosed herein. In one embodiment, the at leastone fungicide is a synthetic fungicide.

The method of the present invention includes the following applicationmethods, namely both of the recombinant exosporium-producing Bacilluscells and the at least one particular insecticide disclosed herein maybe formulated into a single, stable composition with an agriculturallyacceptable shelf life (so called “solo-formulation”), or being combinedbefore or at the time of use (so called “combined-formulations”).

If not mentioned otherwise, the expression “combination” stands for thevarious combinations of the recombinant exosporium-producing Bacilluscells and the at least insecticide, and optionally the at least onefungicide, in a solo-formulation, in a single “ready-mix” form, in acombined spray mixture composed from solo-formulations, such as a“tank-mix”, and especially in a combined use of the single activeingredients when applied in a sequential manner, i.e., one after theother within a reasonably short period, such as a few hours or days,e.g., 2 hours to 7 days. The order of applying the composition accordingto the present invention is not essential for working the presentinvention. Accordingly, the term “combination” also encompasses thepresence of the recombinant exosporium-producing Bacillus cells and theat least one particular insecticide disclosed herein, and optionally theat least one fungicide on or in a plant to be treated or itssurrounding, habitat or storage space, e.g., after simultaneously orconsecutively applying the recombinant exosporium-producing Bacilluscells and the at least one particular insecticide disclosed herein, andoptionally the at least one fungicide to a plant its surrounding,habitat or storage space.

If the recombinant exosporium-producing Bacillus cells and the at leastone particular insecticide disclosed herein, and optionally the at leastone fungicide are employed or used in a sequential manner, it ispreferred to treat the plants or plant parts (which includes seeds andplants emerging from the seed), harvested fruits and vegetablesaccording to the following method: Firstly applying the at least oneparticular insecticide disclosed herein and optionally the at least onefungicide and/or the at least one additional insecticide on the plant orplant parts, and secondly applying the recombinant exosporium-producingBacillus cells to the same plant or plant parts. By this applicationmanner the amount of residues of insecticides/fungicides on the plantupon harvesting is as low as possible. The time periods between thefirst and the second application within a (crop) growing cycle may varyand depend on the effect to be achieved. For example, the firstapplication is done to prevent an infestation of the plant or plantparts with insects, mites, nematodes and/or phytopathogens (this isparticularly the case when treating seeds) or to combat the infestationwith insects, mites, nematodes and/or phytopathogens (this isparticularly the case when treating plants and plant parts) and thesecond application is done to prevent or control the infestation withinsects, mites, nematodes and/or phytopathogens and/or to promote plantgrowth. Control in this context means that the recombinantexosporium-producing Bacillus cells are not able to fully exterminatethe pests or phytopathogenic fungi but are able to keep the infestationon an acceptable level.

The present invention also provides methods of enhancing the killing,inhibiting, preventative and/or repelling activity of the compositionsof the present invention by multiple applications. In some otherembodiments, the compositions of the present invention are applied to aplant and/or plant part for two times, during any desired developmentstages or under any predetermined pest pressure, at an interval of about1 hour, about 5 hours, about 10 hours, about 24 hours, about two days,about 3 days, about 4 days, about 5 days, about 1 week, about 10 days,about two weeks, about three weeks, about 1 month or more. Still in someembodiments, the compositions of the present invention are applied to aplant and/or plant part for more than two times, for example, 3 times, 4times, 5 times, 6 times, 7 times, 8 times, 9 times, 10 times, or more,during any desired development stages or under any predetermined pestpressure, at an interval of about 1 hour, about 5 hours, about 10 hours,about 24 hours, about two days, about 3 days, about 4 days, about 5days, about 1 week, about 10 days, about two weeks, about three weeks,about 1 month or more. The intervals between each application can varyif it is desired. One skilled in the art will be able to determine theapplication times and length of interval depending on plant species,plant pest species, and other factors.

By following the before mentioned steps, a very low level of residues ofthe at least one fungicide and/or at least one particular insecticidedisclosed herein and/or additional insecticide on the treated plant,plant parts, and the harvested fruits and vegetables can be achieved.

If not mentioned otherwise the treatment of plants or plant parts (whichincludes seeds and plants emerging from the seed), harvested fruits andvegetables with the composition according to the invention is carriedout directly or by action on their surroundings, habitat or storagespace using customary treatment methods, for example dipping, spraying,atomizing, irrigating, evaporating, dusting, fogging, broadcasting,foaming, painting, spreading-on, watering (drenching), drip irrigating.It is furthermore possible to apply the recombinant exosporium-producingBacillus cells, the at least one particular insecticide disclosedherein, and optionally the at least one fungicide as solo-formulation orcombined-formulations by the ultra-low volume method, or to inject thecomposition according to the present invention as a composition or assole-formulations into the soil (in-furrow).

The term “plant to be treated” encompasses every part of a plantincluding its root system and the material -e.g., soil or nutritionmedium—which is in a radius of at least 10 cm, 20 cm, 30 cm around thecaulis or bole of a plant to be treated or which is at least 10 cm, 20cm, 30 cm around the root system of said plant to be treated,respectively.

The amount of the recombinant exosporium-producing Bacillus cells whichis used or employed in combination with at least one particularinsecticide disclosed herein, optionally in the presence of at least onefungicide, depends on the final formulation as well as size or type ofthe plant, plant parts, seeds, harvested fruits and vegetables to betreated. Usually, the recombinant exosporium-producing Bacillus cells tobe employed or used according to the invention is present in about 1% toabout 80% (w/w), preferably in about 1% to about 60% (w/w), morepreferably about 10% to about 50% (w/w) of its solo-formulation orcombined-formulation with the at least one particular insecticidedisclosed herein, and optionally the fungicide.

Also the amount of the at least one particular insecticide disclosedherein which is used or employed in combination with the recombinantexosporium-producing Bacillus cells, optionally in the presence of atleast one fungicide, depends on the final formulation as well as size ortype of the plant, plant parts, seeds, harvested fruit or vegetable tobe treated. Usually, the recombinant exosporium-producing Bacillus cellsto be employed or used according to the invention is present in about0.1% to about 80% (w/w), preferably 1% to about 60% (w/w), morepreferably about 10% to about 50% (w/w) of its solo-formulation orcombined-formulation with the at least one particular insecticidedisclosed herein, and optionally the at least one fungicide.

Application of the recombinant exosporium-producing Bacillus cells maybe effected as a foliar spray, as a soil treatment, and/or as a seedtreatment/dressing. When used as a foliar treatment, in one embodiment,about 1/16 to about 5 gallons of whole broth are applied per acre. Whenused as a soil treatment, in one embodiment, about 1 to about 5 gallonsof whole broth are applied per acre. When used for seed treatment about1/32 to about ¼ gallons of whole broth are applied per acre. For seedtreatment, the end-use formulation contains 1×10⁴, at least 1×10⁵, atleast 1×10⁶, 1×10⁷, at least 1×10⁸, at least 1×10⁹, or at least 1×10¹⁰colony forming units per gram.

The recombinant exosporium-producing Bacillus cells and at least oneparticular insecticide disclosed herein, and if present preferably alsothe fungicide are used or employed in a synergistic weight ratio. Theskilled person is able to find out the synergistic weight ratios for thepresent invention by routine methods. The skilled person understandsthat these ratios refer to the ratio within a combined-formulation aswell as to the calculative ratio of the recombinant exosporium-producingBacillus cells described herein and the at least one particularinsecticide disclosed herein when both components are applied asmono-formulations to a plant to be treated. The skilled person cancalculate this ratio by simple mathematics since the volume and theamount of the recombinant exosporium-producing Bacillus cells and the atleast one particular insecticide disclosed herein, respectively, in amono-formulation is known to the skilled person.

The ratio can be calculated based on the amount of the at least oneparticular insecticide disclosed herein, at the time point of applyingsaid component of a combination according to the invention to a plant orplant part and the amount of recombinant exosporium-producing Bacilluscells shortly prior (e.g., 48 h, 24 h, 12 h, 6 h, 2 h, 1 h) or at thetime point of applying said component of a combination according to theinvention to a plant or plant part.

The application of the recombinant exosporium-producing Bacillus cellsand the at least one particular insecticide disclosed herein to a plantor a plant part can take place simultaneously or at different times aslong as both components are present on or in the plant after theapplication(s). In cases where the recombinant exosporium-producingBacillus cells and insecticide are applied at different times andinsecticide is applied noticeable prior to the recombinantexosporium-producing Bacillus cells, the skilled person can determinethe concentration of insecticide on/in a plant by chemical analysisknown in the art, at the time point or shortly before the time point ofapplying the recombinant exosporium-producing Bacillus cells. Viceversa, when the recombinant exosporium-producing Bacillus cells areapplied to a plant first, the concentration of the recombinantexosporium-producing Bacillus cells can be determined using tests whichare also known in the art, at the time point or shortly before the timepoint of applying the insecticide.

In particular, in one embodiment the synergistic weight ratio of therecombinant exosporium-producing Bacillus cells and the at least oneparticular insecticide disclosed herein lies in the range of 1:1000 to1000:1, preferably in the range of 1:500 to 500:1, more preferably inthe range of 1:300 to 500:1. Especially preferred ratios are between20:1 and 1:20, such as 10:1, 5:1 or 2:1. It has to be noted that theseratio ranges refer to the recombinant Bacillus cereus familymember-based biological control agent (to be combined with at least oneparticular insecticide or a preparation of at least one particularinsecticide disclosed herein). For example, a ratio of 100:1 means 100weight parts of a spore preparation of the recombinantexosporium-producing Bacillus-based biological control agent and 1weight part of insecticide are combined (either as a solo formulation, acombined formulation or by separate applications to plants so that thecombination is formed on the plant). In one aspect of this embodiment,the spore preparation of the recombinant exosporium-producing Bacilluscells is a dried spore preparation containing at least about 1×10⁴cfu/g, at least about 1×10⁵ cfu/g, at least about 1×10⁶ cfu/g at leastabout 1×10⁷ cfu/g, at least about 1×10⁸ cfu/g, at least about 1×10⁹cfu/g, at least about 1×10¹⁰ cfu/g, or at least about 1×10¹¹ cfu/g.

In another embodiment, the synergistic weight ratio of the recombinantexosporium-producing Bacillus cells and the at least one particularinsecticide disclosed herein is in the range of 1:100 to 20,000:1,preferably in the range of 1:50 to 10,000:1 or even in the range of 1:50to 1000:1.

In one embodiment of the present invention, the concentration of therecombinant exosporium-producing Bacillus cells after dispersal is atleast 50 g/ha, such as 50-7500 g/ha, 50-2500 g/ha, 50-1500 g/ha; atleast 250 g/ha (hectare), at least 500 g/ha or at least 800 g/ha.

The application rate of composition to be employed or used according tothe present invention may vary. The skilled person is able to find theappropriate application rate by way of routine experiments.

In another aspect of the present invention a seed treated with thecomposition as described above is provided.

The control of insects, mites, nematodes and/or phytopathogens bytreating the seed of plants has been known for a long time and is asubject of continual improvements. Nevertheless, the treatment of seedentails a series of problems which cannot always be solved in asatisfactory manner. Thus, it is desirable to develop methods forprotecting the seed and the germinating plant that remove the need for,or at least significantly reduce, the additional delivery of cropprotection compositions in the course of storage, after sowing or afterthe emergence of the plants. It is desirable, furthermore, to optimizethe amount of active ingredient employed in such a way as to provide thebest-possible protection to the seed and the germinating plant fromattack by insects, mites, nematodes and/or phytopathogens, but withoutcausing damage to the plant itself by the active ingredient employed. Inparticular, methods for treating seed ought also to take intoconsideration the intrinsic insecticidal and/or nematicidal propertiesof pest-resistant or pest-tolerant transgenic plants, in order toachieve optimum protection of the seed and of the germinating plant witha minimal use of crop protection compositions.

The present invention therefore also relates in particular to a methodfor protecting seed and germinating plants from attack by pests, bytreating the seed with the recombinant exosporium-producing Bacilluscells as defined above and at least one particular insecticide disclosedherein in a synergistically effective amount. The method of theinvention for protecting seed and germinating plants from attack bypests encompasses a method in which the seed is treated simultaneouslyin one operation with the recombinant exosporium-producing Bacilluscells and the at least one particular insecticide disclosed herein, andoptionally the at least one fungicide. It also encompasses a method inwhich the seed is treated at different times with the recombinantexosporium-producing Bacillus cells and the at least one particularinsecticide disclosed herein, and optionally the at least one fungicide.

The invention likewise relates to the use of the composition of theinvention for treating seed for the purpose of protecting the seed andthe resultant plant against insects, mites, nematodes and/orphytopathogens.

The invention also relates to seed which at the same time has beentreated with a recombinant exosporium-producing Bacillus cells and atleast one particular insecticide disclosed herein, and optionally atleast one fungicide. The invention further relates to seed which hasbeen treated at different times with the recombinantexosporium-producing Bacillus cells and the at least one particularinsecticide disclosed herein and optionally the at least one fungicideand/or the at least one insecticide. In the case of seed which has beentreated at different times with the recombinant exosporium-producingBacillus cells and the at least one particular insecticide disclosedherein, and optionally the at least one fungicide, the individual activeingredients in the composition of the invention may be present indifferent layers on the seed.

Furthermore, the invention relates to seed which, following treatmentwith the composition of the invention, is subjected to a film-coatingprocess in order to prevent dust abrasion of the seed.

One of the advantages of the present invention is that, owing to theparticular systemic properties of the compositions of the invention, thetreatment of the seed with these compositions provides protection frominsects, mites, nematodes and/or phytopathogens not only to the seeditself but also to the plants originating from the seed, after they haveemerged. In this way, it may not be necessary to treat the crop directlyat the time of sowing or shortly thereafter.

A further advantage is to be seen in the fact that, through thetreatment of the seed with composition of the invention, germination andemergence of the treated seed may be promoted.

It is likewise considered to be advantageous composition of theinvention may also be used, in particular, on transgenic seed.

It is also stated that the composition of the invention may be used incombination with agents of the signalling technology, as a result ofwhich, for example, colonization with symbionts is improved, such asrhizobia, mycorrhiza and/or endophytic bacteria, for example, isenhanced, and/or nitrogen fixation is optimized.

The compositions of the invention are suitable for protecting seed ofany variety of plant which is used in agriculture, in greenhouses, inforestry or in horticulture. More particularly, the seed in question isthat of cereals (e.g., wheat, barley, rye, oats and millet), maize,cotton, soybeans, rice, potatoes, sunflower, coffee, tobacco, canola,oilseed rape, beets (e.g., sugar beet and fodder beet), peanuts,vegetables (e.g., tomato, cucumber, bean, brassicas, onions andlettuce), fruit plants, lawns and ornamentals. Particularly important isthe treatment of the seed of cereals (such as wheat, barley, rye andoats) maize, soybeans, cotton, canola, oilseed rape and rice.

As already mentioned above, the treatment of transgenic seed with thecomposition of the invention is particularly important. The seed inquestion here is that of plants which generally contain at least oneheterologous gene that controls the expression of a polypeptide having,in particular, insecticidal and/or nematicidal properties. Theseheterologous genes in transgenic seed may come from microorganisms suchas Bacillus, Rhizobium, Pseudomonas, Serratia, Trichoderma, Clavibacter,Glomus or Gliocladium. The present invention is particularly suitablefor the treatment of transgenic seed which contains at least oneheterologous gene from Bacillus sp. With particular preference, theheterologous gene in question comes from Bacillus thuringiensis.

For the purposes of the present invention, the composition of theinvention is applied alone or in a suitable formulation to the seed. Theseed is preferably treated in a condition in which its stability is suchthat no damage occurs in the course of the treatment. Generallyspeaking, the seed may be treated at any point in time betweenharvesting and sowing. Typically, seed is used which has been separatedfrom the plant and has had cobs, hulls, stems, husks, hair or pulpremoved. Thus, for example, seed may be used that has been harvested,cleaned and dried to a moisture content of less than 15% by weight.Alternatively, seed can also be used that after drying has been treatedwith water, for example, and then dried again.

When treating seed it is necessary, generally speaking, to ensure thatthe amount of the composition of the invention, and/or of otheradditives, that is applied to the seed is selected such that thegermination of the seed is not adversely affected, and/or that the plantwhich emerges from the seed is not damaged. This is the case inparticular with active ingredients which may exhibit phytotoxic effectsat certain application rates.

The compositions of the invention can be applied directly, in otherwords without comprising further components and without having beendiluted. As a general rule, it is preferable to apply the compositionsin the form of a suitable formulation to the seed. Suitable formulationsand methods for seed treatment are known to the skilled person and aredescribed in, for example, the following documents: U.S. Pat. Nos.4,272,417 A; 4,245,432 A;

4,808,430 A; 5,876,739 A; U.S. Patent Publication No. 2003/0176428 A1;WO 2002/080675 A1; WO 2002/028186 A2.

The combinations which can be used in accordance with the invention maybe converted into the customary seed-dressing formulations, such assolutions, emulsions, suspensions, powders, foams, slurries or othercoating compositions for seed, and also ULV formulations.

These formulations are prepared in a known manner, by mixing compositionwith customary adjuvants, such as, for example, customary extenders andalso solvents or diluents, colorants, wetters, dispersants, emulsifiers,antifoams, preservatives, secondary thickeners, stickers, gibberellins,and also water.

Colorants which may be present in the seed-dressing formulations whichcan be used in accordance with the invention include all colorants whichare customary for such purposes. In this context it is possible to usenot only pigments, which are of low solubility in water, but alsowater-soluble dyes. Examples include the colorants known under thedesignations Rhodamin B, C.I. Pigment Red 112 and C.I. Solvent Red 1.

Wetters which may be present in the seed-dressing formulations which canbe used in accordance with the invention include all of the substanceswhich promote wetting and which are customary in the formulation ofactive agrochemical ingredients. Use may be made preferably ofalkylnaphthalenesulphonates, such as diisopropyl-ordiisobutyl-naphthalenesulphonates.

Dispersants and/or emulsifiers which may be present in the seed-dressingformulations which can be used in accordance with the invention includeall of the nonionic, anionic and cationic dispersants that are customaryin the formulation of active agrochemical ingredients. Use may be madepreferably of nonionic or anionic dispersants or of mixtures of nonionicor anionic dispersants. Suitable nonionic dispersants are, inparticular, ethylene oxide-propylene oxide block polymers, alkylphenolpolyglycol ethers and also tristryrylphenol polyglycol ethers, and thephosphated or sulphated derivatives of these. Suitable anionicdispersants are, in particular, lignosulphonates, salts of polyacrylicacid, and arylsulphonate-formaldehyde condensates.

Antifoams which may be present in the seed-dressing formulations whichcan be used in accordance with the invention include all of the foaminhibitors that are customary in the formulation of active agrochemicalingredients. Use may be made preferably of silicone antifoams andmagnesium stearate.

Preservatives which may be present in the seed-dressing formulationswhich can be used in accordance with the invention include all of thesubstances which can be employed for such purposes in agrochemicalcompositions. Examples include dichlorophen and benzyl alcoholhemiformal.

Secondary thickeners which may be present in the seed-dressingformulations which can be used in accordance with the invention includeall substances which can be used for such purposes in agrochemicalcompositions. Those contemplated with preference include cellulosederivatives, acrylic acid derivatives, xanthan, modified clays andhighly disperse silica.

Stickers which may be present in the seed-dressing formulations whichcan be used in accordance with the invention include all customarybinders which can be used in seed-dressing products. Preferred mentionmay be made of polyvinylpyrrolidone, polyvinyl acetate, polyvinylalcohol and tylose.

Gibberellins which may be present in the seed-dressing formulationswhich can be used in accordance with the invention include preferablythe gibberellins A1, A3 (=gibberellic acid), A4 and A7, with gibberellicacid being used with particular preference. The gibberellins are known(cf. R. Wegler, “Chemie der Pflanzenschutz-andSchadlingsbekampfungsmittel”, Volume 2, Springer Verlag, 1970, pp.401-412).

The seed-dressing formulations which can be used in accordance with theinvention may be used, either directly or after prior dilution withwater, to treat seed of any of a wide variety of types. Accordingly, theconcentrates or the preparations obtainable from them by dilution withwater may be employed to dress the seed of cereals, such as wheat,barley, rye, oats and triticale, and also the seed of maize, rice,oilseed rape, peas, beans, cotton, sunflowers and beets, or else theseed of any of a very wide variety of vegetables. The seed-dressingformulations which can be used in accordance with the invention, ortheir diluted preparations, may also be used to dress seed of transgenicplants. In that case, additional synergistic effects may occur ininteraction with the substances formed through expression.

For the treatment of seed with the seed-dressing formulations which canbe used in accordance with the invention, or with the preparationsproduced from them by addition of water, suitable mixing equipmentincludes all such equipment which can typically be employed for seeddressing. More particularly, the procedure when carrying out seeddressing is to place the seed in a mixer, to add the particular desiredamount of seed-dressing formulations, either as such or followingdilution with water beforehand, and to carry out mixing until thedistribution of the formulation on the seed is uniform. This may befollowed by a drying operation.

The application rate of the seed-dressing formulations which can be usedin accordance with the invention may be varied within a relatively widerange. It is guided by the particular amount of the recombinantexosporium-producing Bacillus cereus family member-based biologicalcontrol agent and the at least one particular insecticide disclosedherein in the formulations, and by the seed. The application rates inthe case of the composition are situated generally at between 0.001 and50 g per kilogram of seed, preferably between 0.01 and 15 g per kilogramof seed.

The compositions according to the invention, in case they exhibitinsecticidal and miticidal and/or nematicidal activity, in combinationwith good plant tolerance and favourable toxicity to warm-bloodedanimals and being tolerated well by the environment, are suitable forprotecting plants and plant organs, for increasing harvest yields, forimproving the quality of the harvested material and for controllinganimal pests, in particular insects, mites, arachnids, helminths,nematodes and molluscs, which are encountered in agriculture, inhorticulture, in animal husbandry, in forests, in gardens and leisurefacilities, in protection of stored products and of materials, and inthe hygiene sector.

The fact that the composition is well tolerated by plants at theconcentrations required for controlling plant diseases and pests allowsthe treatment of above-ground parts of plants, of propagation stock andseeds, and of the soil.

According to the invention all plants and plant parts can be treated. Byplants is meant all plants and plant populations such as desirable andundesirable wild plants, cultivars and plant varieties (whether or notprotectable by plant variety or plant breeder's rights). Cultivars andplant varieties can be plants obtained by conventional propagation andbreeding methods which can be assisted or supplemented by one or morebiotechnological methods such as by use of double haploids, protoplastfusion, random and directed mutagenesis, molecular or genetic markers orby bioengineering and genetic engineering methods. By plant parts ismeant all above ground and below ground parts and organs of plants suchas shoot, leaf, blossom and root, whereby for example leaves, needles,stems, branches, blossoms, fruiting bodies, fruits and seed as well asroots, corms and rhizomes are listed. Crops and vegetative andgenerative propagating material, for example cuttings, corms, rhizomes,runners and seeds also belong to plant parts.

The inventive composition, when it is well tolerated by plants, hasfavourable homeotherm toxicity and is well tolerated by the environment,is suitable for protecting plants and plant organs, for enhancingharvest yields, for improving the quality of the harvested material. Itcan preferably be used as crop protection composition. It is activeagainst normally sensitive and resistant species and against all or somestages of development.

Plants which can be treated in accordance with the invention include thefollowing main crop plants: maize, soya bean, alfalfa, cotton,sunflower, Brassica oil seeds such as Brassica napus (e.g., canola,rapeseed), Brassica rapa, B. juncea (e.g., (field) mustard) and Brassicacarinata, Arecaceae sp. (e.g., oilpalm, coconut), rice, wheat, sugarbeet, sugar cane, oats, rye, barley, millet and sorghum, triticale,flax, nuts, grapes and vine and various fruit and vegetables fromvarious botanic taxa, e.g., Rosaceae sp. (e.g., pome fruits such asapples and pears, but also stone fruits such as apricots, cherries,almonds, plums and peaches, and berry fruits such as strawberries,raspberries, red and black currant and gooseberry), Ribesioidae sp.,Juglandaceae sp., Betulaceae sp., Anacardiaceae sp., Fagaceae sp.,Moraceae sp., Oleaceae sp. (e.g., olive tree), Actinidaceae sp.,Lauraceae sp. (e.g., avocado, cinnamon, camphor), Musaceae sp. (e.g.,banana trees and plantations), Rubiaceae sp. (e.g., coffee), Theaceaesp. (e.g., tea), Sterculiceae sp., Rutaceae sp. (e.g., lemons, oranges,mandarins and grapefruit); Solanaceae sp. (e.g., tomatoes, potatoes,peppers, capsicum, aubergines, tobacco), Liliaceae sp., Compositae sp.(e.g., lettuce, artichokes and chicory—including root chicory, endive orcommon chicory), Umbelliferae sp. (e.g., carrots, parsley, celery andceleriac), Cucurbitaceae sp. (e.g., cucumbers—including gherkins,pumpkins, watermelons, calabashes and melons), Alliaceae sp. (e.g.,leeks and onions), Cruciferae sp. (e.g., white cabbage, red cabbage,broccoli, cauliflower, Brussels sprouts, pak choi, kohlrabi, radishes,horseradish, cress and chinese cabbage), Leguminosae sp. (e.g., peanuts,peas, lentils and beans—e.g., common beans and broad beans),Chenopodiaceae sp. (e.g., Swiss chard, fodder beet, spinach, beetroot),Linaceae sp. (e.g., hemp), Cannabeacea sp. (e.g., cannabis), Malvaceaesp. (e.g., okra, cocoa), Papaveraceae (e.g., poppy), Asparagaceae (e.g.,asparagus); useful plants and ornamental plants in the garden and woodsincluding turf, lawn, grass and Stevia rebaudiana; and in each casegenetically modified types of these plants.

Depending on the plant species or plant cultivars, their location andgrowth conditions (soils, climate, vegetation period, diet), using oremploying the composition according to the present invention thetreatment according to the invention may also result in super-additive(“synergistic”) effects. Thus, for example, by using or employinginventive composition in the treatment according to the invention,reduced application rates and/or a widening of the activity spectrumand/or an increase in the activity better plant growth, increasedtolerance to high or low temperatures, increased tolerance to drought orto water or soil salt content, increased flowering performance, easierharvesting, accelerated maturation, higher harvest yields, biggerfruits, larger plant height, greener leaf color, earlier flowering,higher quality and/or a higher nutritional value of the harvestedproducts, higher sugar concentration within the fruits, better storagestability and/or processability of the harvested products are possible,which exceed the effects which were actually to be expected.

At certain application rates of the inventive composition in thetreatment according to the invention may also have a strengtheningeffect in plants. The defense system of the plant against attack byunwanted phytopathogenic fungi and/or microorganisms and/or viruses ismobilized. Plant-strengthening (resistance-inducing) substances are tobe understood as meaning, in the present context, those substances orcombinations of substances which are capable of stimulating the defensesystem of plants in such a way that, when subsequently inoculated withunwanted phytopathogenic fungi and/or microorganisms and/or viruses, thetreated plants display a substantial degree of resistance to thesephytopathogenic fungi and/or microorganisms and/or viruses. Thus, byusing or employing composition according to the present invention in thetreatment according to the invention, plants can be protected againstattack by the abovementioned pathogens within a certain period of timeafter the treatment. The period of time within which protection iseffected generally extends from 1 to 10 days, preferably 1 to 7 days,after the treatment of the plants with the active compounds.

Plants and plant cultivars which are also preferably to be treatedaccording to the invention are resistant against one or more bioticstresses, i.e., said plants show a better defense against animal andmicrobial pests, such as against nematodes, insects, mites,phytopathogenic fungi, bacteria, viruses and/or viroids.

Plants and plant cultivars which may also be treated according to theinvention are those plants which are resistant to one or more abioticstresses, i.e., that already exhibit an increased plant health withrespect to stress tolerance. Abiotic stress conditions may include, forexample, drought, cold temperature exposure, heat exposure, osmoticstress, flooding, increased soil salinity, increased mineral exposure,ozone exposure, high light exposure, limited availability of nitrogennutrients, limited availability of phosphorus nutrients, shadeavoidance. Preferably, the treatment of these plants and cultivars withthe composition of the present invention additionally increases theoverall plant health (cf. above).

Plants and plant cultivars which may also be treated according to theinvention, are those plants characterized by enhanced yieldcharacteristics, i.e., that already exhibit an increased plant healthwith respect to this feature. Increased yield in said plants can be theresult of, for example, improved plant physiology, growth anddevelopment, such as water use efficiency, water retention efficiency,improved nitrogen use, enhanced carbon assimilation, improvedphotosynthesis, increased germination efficiency and acceleratedmaturation.

Yield can furthermore be affected by improved plant architecture (understress and non-stress conditions), including but not limited to, earlyflowering, flowering control for hybrid seed production, seedling vigor,plant size, internode number and distance, root growth, seed size, fruitsize, pod size, pod or ear number, seed number per pod or ear, seedmass, enhanced seed filling, reduced seed dispersal, reduced poddehiscence and lodging resistance. Further yield traits include seedcomposition, such as carbohydrate content, protein content, oil contentand composition, nutritional value, reduction in anti-nutritionalcompounds, improved processability and better storage stability.Preferably, the treatment of these plants and cultivars with thecomposition of the present invention additionally increases the overallplant health (cf. above).

Plants that may be treated according to the invention are hybrid plantsthat already express the characteristic of heterosis or hybrid vigorwhich results in generally higher yield, vigor, health and resistancetowards biotic and abiotic stress factors. Such plants are typicallymade by crossing an inbred male-sterile parent line (the female parent)with another inbred male-fertile parent line (the male parent). Hybridseed is typically harvested from the male sterile plants and sold togrowers. Male sterile plants can sometimes (e.g., in corn) be producedby detasseling, i.e., the mechanical removal of the male reproductiveorgans (or males flowers) but, more typically, male sterility is theresult of genetic determinants in the plant genome. In that case, andespecially when seed is the desired product to be harvested from thehybrid plants it is typically useful to ensure that male fertility inthe hybrid plants is fully restored. This can be accomplished byensuring that the male parents have appropriate fertility restorer geneswhich are capable of restoring the male fertility in hybrid plants thatcontain the genetic determinants responsible for male-sterility. Geneticdeterminants for male sterility may be located in the cytoplasm.Examples of cytoplasmic male sterility (CMS) were for instance describedin Brassica species. However, genetic determinants for male sterilitycan also be located in the nuclear genome. Male sterile plants can alsobe obtained by plant biotechnology methods such as genetic engineering.A particularly useful means of obtaining male-sterile plants isdescribed in WO 89/10396 in which, for example, a ribonuclease such asbarnase is selectively expressed in the tapetum cells in the stamens.Fertility can then be restored by expression in the tapetum cells of aribonuclease inhibitor such as barstar.

Plants or plant cultivars (obtained by plant biotechnology methods suchas genetic engineering) which may be treated according to the inventionare herbicide-tolerant plants, i.e., plants made tolerant to one or moregiven herbicides. Such plants can be obtained either by genetictransformation, or by selection of plants containing a mutationimparting such herbicide tolerance.

EXAMPLES Example 1 Formula for the Efficacy of the Combination ofMultiple Active Ingredients

A synergistic effect of active ingredients is present when the activityof the active ingredient combinations exceeds the total of theactivities of the active ingredients when applied individually. Theexpected activity for a given combination of two active ingredients canbe calculated as follows (cf. Colby, S. R., “Calculating Synergistic andAntagonistic Responses of Herbicide Combinations,” Weeds, 1967, 15,20-22):

If

-   -   X is the efficacy when active ingredient A is applied at an        application rate of m ppm (or g/ha),    -   Y is the efficacy when active ingredient B is applied at an        application rate of n ppm (or g/ha),    -   E is the efficacy when the active ingredients A and B are        applied at application rates of m and n ppm (or g/ha),        respectively, and    -   then

$E = {X + Y - \frac{X \cdot Y}{100}}$

If the actual activity exceeds the calculated value, then the activityof the combination is superadditive, i.e., a synergistic effect exists.In this case, the efficacy which was actually observed must be greaterthan the value for the expected efficacy (E) calculated from theabove-mentioned formula.

For instance, the formula and analysis can be applied to an evaluationof plant growth promotion. Such an assay is evaluated several days afterthe applications to plants. 100% means plant weight which corresponds tothat of the untreated control plant. Efficacy means in this case theadditional % of plant weight in comparison to that of the untreatedcontrol. For example, a treatment that resulted in plant weights thatwere 120% compared to the untreated control plant would have an efficacyof 20%. If the plant growth promotion effect for the combination (i.e.,the observed efficacy for % plant weights of plants treated with thecombination) exceeds the calculated value, then the activity of thecombination is superadditive, i.e., a synergistic effect exists.

The formula and analysis can also be used to evaluate synergy in diseasecontrol assays. The degree of efficacy expressed in % is denoted. 0%means an efficacy which corresponds to that of the control while anefficacy of 100% means that no disease is observed.

If the actual insecticidal or fungicidal activity exceeds the calculatedvalue, then the activity of the combination is superadditive, i.e., asynergistic effect exists. In this case, the efficacy which is actuallyobserved must be greater than the value for the expected efficacy (E)calculated from the above-mentioned formula.

A further way of demonstrating a synergistic effect is the method ofTammes (cf. “Isoboles, A Graphic Representation of Synergism inPesticides” in Neth. J. Plant Path., 1964, 70, 73-80).

Example 2 Plant Growth Promotion with Flupyradifurone and RecombinantBacillus thuringiensis Cells

Experiments were conducted to analyze efficacy of a combination offlupyradifurone and a fermentation product of recombinant Bacillusthuringiensis cells expressing phospholipase C (“BEPC”). Maize seedswere grown in sterile mixture of synthetic media and sand in smallthree-inch square pots on light racks in a plant growth room at 25-28°C. and 50% humidity for about 14 days. Two seeds were planted in eachpot. At planting, the growing media in each pot was drenched with thetreatments described below. After 14 days, plants were measured forwhole plant biomass. In the tables below, UTC refers to untreatedcontrol. “Calculated” refers to the expected effect calculated using theabove-described Colby equation and “Efficacy” refers to the actualeffect observed.

The SIVANTO® product, which contains flupyradifurone as its activeingredient (17.09% flupyradifurone), was diluted in 50 mL water and thediluted solution was used to drench the growing media. The applicationrate shown below refers to the amount of active ingredient (i.e.,flupyradifurone) applied to the growing media.

A recombinant Bacillus cereus family member (Bacillus thuringiensisBT013A) expressing phospholipase C on its exosporium (BEPC) wasgenerated as follows. To generate plasmids for expression of fusionproteins in Bacillus cereus family members, PCR fragments were generatedthat encoded the BclA promoter (SEQ ID NO: 85), a methionine startcodon, and amino acids 20-35 of BclA (SEQ ID NO: 1) followed by a sixalanine linker sequence fused in frame to Bacillus thuringiensis BT013Aphospholipase (SEQ ID NO: 108). These PCR fragments were digested withXhoI and ligated into the SalI site of the pSUPER plasmid to generatethe plasmids pSUPER-BclA 20-35-Phospholipase. The pSUPER plasmid wasgenerated through fusion of the pUC57 plasmid (containing an ampicillinresistance cassette) with the pBC16-1 plasmid from Bacillus (containinga tetracycline resistance). This 5.5 kbp plasmid can replicate in bothE. coli and Bacillus spp. The pSUPER-BclA 20-35-Phospholipase plasmidswere transformed into and propagated in dam methylase negative E. colistrains and finally were transformed into Bacillus thuringiensis BT013A.

To obtain whole broth cultures of BEPC, 15 mL conicals containing brainheart infusion media (BHI) were inoculated with BEPC and grown for 7-8hours at around 30° C. at a shaker setting of 300 rpm. The next day, 250μL aliquots from each flask were inoculated into 250 mL flaskscontaining 50 mL of a yeast extract-based media and grown at about 30°C. After approximately 2 days of incubation, when sporulation was atleast 95% completed, the culture broth was harvested and colony formingunits calculated. The fermentation broth was diluted to 5% in 50 mLwater and the following colony forming units applied to each pot.

TABLE 3 Whole Plant Application Biomass Treatment Rate (g) Found %Efficacy % Calculated % UTC 3.39 100 Flupyradifurone 1.36 mg/pot 3.50103 3 BEPC 5% 7 × 10⁸ 3.83 113 13 CFU/pot Flupyradifurone + 1.36mg/pot + 4.15 122 22 15.61 BEPC 5% 7 × 10⁸ CFU/pot

Results indicate a superadditive plant yield effect when combiningflupyradifurone and BEPC.

Example 3 Plant Growth Promotion with Clothianidin and RecombinantBacillus thuringiensis Cells

Maize seeds will be grown in loamy sand in the greenhouse at 20° C. and70% humidity for about 11 days. After about 11 days from the time oftreatment the seedlings will be cut off above the soil and the freshweight will be determined.

Recombinant Bacillus thuringiensis cells expressing an endoglucanaseencoded by SEQ ID NO: 107 or a phospholipase C encoded by SEQ ID NO: 108and prepared as described above will be applied at about 50 μg/kernel.Clothianidin will also be applied at about 250 μg/kernel.

It is expected that the maize plants treated with the recombinantBacillus thuringiensis in combination with the clothianidin will have %shoot weights that exceed the calculated value based on the % shootweights from the maize plants treated with the two active ingredientsalone, i.e., a synergistic effect will be observed.
